Abstract:
Objective To explore the image features of benign fibrous histiocytoma of bone and its correlative differential diagnosis.Methods Nine cases of benign fibrous histiocytoma of bone were retrospectively analyzed by comparing the imaging findings with surgical and pathological results.Results In all 9 cases,the tumors were single,ranged from 10 mm?15 mm?20 mm to 50 mm?50 mm?60 mm in diameter,which appeared as round or oval destruction with clear border in the bone,neither calcification nor ossification.The border of tumors in 5 cases was accompanied by integrated sclerosis ring with homogeneous thickness.There were expanding changes in 6 cases,no expanding changes in 3 cases.4 cases underwent MRI,2 cases were homogeneous,low signal on both T1WI and T2WI,and 2 cases were low signal on T1WI and high signal on T2WI with low signal sclerosis ring in circumference.There were no periosteum reaction and soft-tissue tumor in 9 cases.Conclusion X-ray,CT and MRI are valuable in the diagnosis of benign fibrous histiocytoma of bone,for some typical cases,the correctly diagnosis of it can be made before operation.
